The Department of Energy has announced that 93 and 95 octane petrol will increase by 1 cent per litre from next Wednesday.
There will, however, be decreases in diesel and liquefied petroleum gas.
The price of diesel will decrease by between 1.8 and 3.8 cents per litre.
The wholesale price of illuminating paraffin will increase by 1 cent a litre, while the maximum retail price for LP GAS will decrease by 4c a kilogram.
The department said the main reasons for the fuel price adjustments was the weakening of the rand against the dollar, despite the drop in the prices of all petroleum products during the period under review.
